Alas, it will have been months since I've heard a Kemper by then. I'll basically be able to post whether I'm happy or not, for whatever that's worth. I'll probably compare it directly with Bias Amps and offer my opinions there.
As for the ease/difficulty of a Kemper, it depends on how you intend to use it. If you're just running one signal path (4 stomps, 1 amp, and some post effects) and using a footcontroller to select presets, it will deliver. And yes it sounds amazing and can be made to sound like just about anything you want through the acquisition of new profiles. I need a few things that 95% of guitarists have no interest in, which made me the token malcontent amongst Kemper-owners LOL. But the KPA might serve you very well.
If, on the other hand, you want real flexibility with effects, routing, expression pedal assignments, USB integration, multiple amps, etc... then the Kemper may fall short regardless of how good it sounds.
